External Dependency Bug Announcement

For RHEL 7 and CentOS 7 users: Version 1.10.3-3.el7.x86_64 of the
OpenMPI RPM is known to have a bug that impacts the usability of
SST. Under certain configurations, SST users may encounter the
following error:

Per the comments in the bug report, a fix is not expected until
release 7.4 of RHEL/CentOS 7.

We recommend avoiding the installation of the OpenMPI RPM version
openmpi-1.10.3-3.el7.x86. If this is not possible, we recommend
building the latest OpenMPI 1.10 from source and using it, which
alleviates this problem. The source code for OpenMPI 1.10 is
available here.

Instructions for building OpenMPI 1.10 are essentially the same
as for building OpenMPI 1.8.8, substituting for the package
version where necessary.
